 additional tests:
 

-* maxsize(size)
-
-  Tests whether the attachment is no larger than the specified size.
-  The size defaults to being in bytes, but "kb", "mb", "gb" etc can be
-  used to specify the units.
+* "`maxsize(size)`" - tests whether the attachment is no larger than the
+  specified size. The size defaults to being in bytes, but "kb", "mb", "gb"

-* minsize(size)
-
-  Tests whether the attachment is no smaller than the specified size.
+* "`minsize(size)`" - tests whether the attachment is no smaller than the

-* ispage()
-
-  Tests whether the attachment will be treated by ikiwiki as a wiki page.
-  (Ie, if it has an extension of ".mdwn", or of any other enabled page
